PATENT BUNG.

srEcIrIc-Arron forming m of'L'etters Patent No. 614,603, dated November 22, lacs.

Application filed August 29 f 1896.

To all whom it may concern.-

Be it known that I, J OSEPH P. BAUMGART- NER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Bungs, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of an improved construction of bung in which provision is made for expanding the same by actuating a plurality of bolts which engage the inner surface of the cask or barrel to which the bung is applicable.

It also consists of a novel construction of appliances whereby air is readily admitted to the interior of the cask through the bung when desired.

It also consists of a novel construct-ion of expansible ring employed common to the bung and its bushing.

It further consists of novel details of construction, all as will be hereinafter set forth, and specifically pointed out in the claims.

Figure 1 represents a plan view of a bung embodying my invention, showing the bushing and a portion of a cask or a barrel to which the same is applicable. Fig. 2 represents a bottom plan view of the bung seen in Fig. 1. Fig. 3 represents a partial section on line 00 Q3, Fig. 2, showing the bung in elevation and the bushing and cask in section. Fig. 4 represents a section through the bung on the line as m, Fig. 2, showing the hung in section and the bushing and cask removed. Fig. 5 represents a portion of the bung seen in Fig. 4, and a sectional view of the device for causing admission of air to the interior of the cask. Fig. 6 represents a sectional View of the interior portion of the bung seen in Fig. 4, showing the air-admitting device in a different position and admitting air to the interior of the cask. Fig. 7 represents a section on line 3 3 Fig. 3, showing the bolts employed and the means for actuating the same. Fig. 8 represents a sectional view of the outer portion of the bung, showing a special form of expansible ring. Figs. 9 and 10 represent side elevations of the left-hand or inner end of the bung seen in Figs. 3 and Serial No. 604,251. (No model.)

4, showing different forms of bolts which may be employed. Fig. 11 represents a sectional View of the key or wrench employed. Fig. 12 represents a section on line .2 2, Fig. 11.

Similarletters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a portion of a cask or barrel, and B designates a bushing'secured thereto, said bushing having tapering walls 0, threaded externally and being provided with the flange D, which engages the outer portion of the cask, the outer portion of the bushing being provided with the annular recess or seat E, the function of which will be hereinafter explained.

F designates the body of the bung, the same having a portion G of reduced diameter,

whereby the shoulderH and the flange J are formed, between which is held the ring K, of rubber or other compressible material, said ring havinga suitable body and the rounded or beaded portion M, which is seated in said recess E, while that part of the ring underneath the flange J is provided with an annular concavity or recess L, the function of which will be explained.

,N designates a plug employed, the same being located within the bushing and having a body portion of substantially uniform diameter which contacts with the annular ribs P and Q of the bung, said plug being provided with a fiange R, between which and the rib Q is located the washer or packing S, the inner extremity of the plug N being provided with a pinion T, whose teeth intermesh with the teeth of the racks U, which latter are attached to the bolts V so as to be opposite to each other, said bolts having a recessed portion NV and an inclined portion or edge X, the relative location of which will be apparent from Fig. 4, it being evident that any rotation of the pinion T will cause the bolts V to move toward or away from each other, and thus be disengaged from or caused to engage the interior wall of the cask or barrel A, as will be evident from Fig. 3, the movement of said bolts being limited by the stops U which contact with the rim U of the bung or the lugs Z The bolts V are held in position against the body of the bung,

and their racks are kept in engagement with the pinion T by means of the plate or cap Y, which latter is held in position by the screw Z, which engages the lugs Z (Seen in Fig. 7.)

A designates a washer or packing which is located within a suitable seat in the cap Y, against which packing the extremity of the plug N contacts. B designates a cavity in said cap Y, in which is located the disk 0, the latter having a washer D interposed between it and the base of said cavity.

E designates a cap which engages the walls surrounding the cavity B, said cap being pro vided with the ports F, which open into the interior of the cask.

G designates a spring interposed between the disk 0 and cap E, said disk 0 having the stem H projecting toward the interior of the cask and through the top of the cap E, while from the opposite side of said disk the stem J projects, the same passing through the bottom of the cavity B, the washers A B',and the plug N, said latter stem being provided with a longitudinally-extending recess or Vent K, by means of which air can be admitted from the exterior to the cavity B and thence to the interior of the cask, when the stem J and disk 0 are caused to assume the position seen in Fig. (3.

L designates a cap which is provided with the lips M, which are adapted to engage the under side of the head P of the plug N, said head having a recessed portion N thereunder, as will be evident from Fig. 4, and being provided with the oppositely-located recesses Q", the location of which will be apparent from Figs. 1 and 4.

Q designates a threaded stem which passes through the cap or head L and is provided with the head R, by means of which said screw can be readily manipulated so that the stem Q can engage and depress the stem J, whereupon the parts will assume the position seen in Figs. 5 and 6.

S and T designate different forms which may be given to bolts V, as will be understood from Figs. 9 and 10, the bolt S being provided with an offset S while the bolt T is provided with a greater bevel 01' inclination than any of the others in order to enable the same to readily engage the interior wall or su rface of the cask in which the bung is located.

V designates a wrench or key by means of which the plug N is rotated, said key having a body portion V and the handle V and being provided with a cavity U in its end, the inner wall of which has on its inner face the lugs X and the raised portions Y and the adjacent recessed portions Y underneath the same, which are adapted to coaet with the head P so that upon placing the key upon the head P and giving the same a partial r0- tation the head and key will be interlocked, so that the plug N may be rotated in either direction.

The operation is as follows: The bung havei4,eos

ing been placed in position in its bushing, the bolts V being in the position indicated in Fig. 4, it will be seen that it the plug N be turned in the proper direction the engagement of the pinion 'l. with the contiguous racks will cause the bolts V to move outwardly into the position seen in Fig. 3, said bolts by their contact with the inner surface of the cask thereby pulling the ring K inwardly against the tapering walls of the bushing and simultaneously compressing said ring and causing the outer portion thereof to seat in the annular concavity or seat E of the bushing, said outer portion of said ring being held in position by means of the flange J, and the parts now assuming the position seen in Fig. When it is desired to remove the bung, the plug N is rotated in the opposite direction, thus causing the bolts V to assume the position seen in Fig. 4, whereupon by reason of the resiliency of the ring K the latter will assume the shape seen in Figs. 4, 5, and 8 again. The bolts S or T may be used in place of the bolts V, according to requirements, the operation of the hung in other respects being the same. When the parts are in the position seen in Fig. 4, the pressure of the spring G' against the disk 0 will hold the latter in the position seen, and when for any reason it is desired to equalize the pressure within the cask with the exterior air it is only necessary to place the head L in the position seen in Fig. 5 and screw the stem Q into contact with the stem J, whereupon the latter and the disk 0 will appear as seen in Fig. 6, and air can readily escape into the interior of the cask, as is evident.

It will of course be understood that the vent K maybe dispensed with, if desired, in which case the cap E and the cavity 13 can also be dispensed with.

It will further be apparent that the ring seen in Fig. 8 is especially applicable to the bushing seen in Fig. 3, since the rounded or beaded portion M seats in the annular recess E, while the rings seen in Figs. 4 and 5 are applicable to any bushing, the rings in each instance being substantially the same with the exception of the beaded portion of the bung, being identical in each instance.

It will further be understood that changes may be made by those skilled in the art which will come within the scope of my invention, and I do not, therefore, desire to be limited in every instance to the exact construction shown and described.
